What is the difference between fixed-price and cost-reimbursable contracts?

• A. Fixed-price contracts reimburse actual costs plus a fee; cost-reimbursable contracts set a fixed price.
• B. Fixed-price contracts are always safer for buyers.
• C. Fixed-price contracts are for services; cost-reimbursable are for goods.
• D. Fixed-price contracts set a fixed total price regardless of actual costs; cost-reimbursable contracts reimburse actual costs plus a fee; risk allocation differs.

Answer: (D)

The key idea is how price and risk are handled in the contract types. A fixed-price contract locks in a single total price for a defined scope, and that price doesn’t change no matter what actual costs the seller incurs (though changes in scope can trigger adjustments). This arrangement shifts most cost risk to the seller: if costs run higher than expected, the seller absorbs the loss, but if costs are lower, the seller may earn more profit. Buyers gain price certainty and potential savings if the seller manages costs well. In contrast, a cost-reimbursable contract reimburses the seller for actual allowable costs incurred, plus a fee. Since the buyer covers the costs, there is less incentive for the seller to cut expenses, and the buyer takes on the risk of cost overruns. This type is favored when the project scope is uncertain or difficult to estimate, and close oversight is needed to manage spend. That difference—fixed total price versus reimbursement of costs plus fee, with corresponding shifts in risk—is why the option describing those characteristics is the best choice. The other statements misstate how these contracts work or when they’re used.
